Abstract

An outboard motor includes a case extending generally vertically and supported on a hull. An engine is supported at an upper end of the case. A propeller is supported by a lower end of the case. A drive shaft is supported within the case for rotation about a generally vertical axis. The driveshaft has an upper end operatively connected to the engine and a lower end operatively connected to the propeller. An upper portion of the case includes an elongate extruded portion having substantially the same cross-sectional shape along its length.
